Sergio, could you clarify this: have you managed to install Ubuntu yet, or is it just Windows for now? If the first: do you think the Ubuntu installation broke Windows?

No. I've used Ubuntu before, alongside with windows, but with another Laptopt. My Toshiba doesn't work (But it has nothing to do with Ubuntu). A few weeks ago it showed me the "startup repair is checking your system for problems" and then it says that it couldn't fix the problem, and doesn't start windows. So, I'm asking if I can install Ubuntu with these conditions.

It seems like that your windows installation is corrupt. Do you want to keep windows?

If you want to keep the Windows system, you may install Ubuntu 12.04 LTS on a VM (virtual machine).

If you want to remove the Windows system and reinstall Ubuntu 12.4, you just need boot your laptop on ubuntu DVD, click Install Ubuntu, provide the information requested by the installer, and let the installer install the OS.
